This invention relates toen automobile bumper and more particularlyto a type of bum er having :an impactbar of. considr erab e width formed to As is well known in the yart, it has been l f l lthe practice heretofore to secure the end of the attaching bar or bars and the impact section of a bumper together `by means of 1 lessening the-number of parts.'

Another object `is to provide aY bumper formed L of relatively thin .material which may be rolled into the desired shape ineX- m pensively and (permit expeditious assemblyl of the parts an be pleasing tothe eye. y A `clear conceptionof the construction and further obects `ofthe invention `may be `had from the ollowing specication `inconjunc-` 'm tion with the `accompanying drawings in which y Fig. 1 discloses the'invention v1n front elevation.

The now preferred vform of invention Las "shown in Figs. 1 and 2comprise's animbari-is -formed as shown `with v itsf'certer cured to t e 4impact member 1' by an emblem-headed bolt 3.". The ends of bar 2 are secured to the ends "of impact bar 1b bolts 1w 4.

In thistype Vbum er theg'roove' 6 is formed in `they rear of relativelythin strip steel, which is rolled in the u shape as shown in Fig. "3.; flanges 5 at the top and bottom and a ltfing'i` tudinal groove` 6 extending `along the mid le of theban Thegrooved portion 6 preferably left unfinished except lforfa'coating of enamel while the two remaining faces of the bar arerground Vand"niclreled, or p finished in any desired manner.

` The irmemst member is formed with loop p end sfas shown, thereby -bringingthe groove 6 to the rear ofjthebumpen The rearI bar 2" is of "a width equal to the groove Gand fixed therein and is held by a boltsuch as 4:6. Due 'tof the Vfact thatthe bar 2`is heated in the groove 6 g portion and fits snugly therein, it is held 1n `horizontalalignment with the impact bar without the necessity of using clamps, thereby givin fewer parts toghe assembled. The bolt `3 asa ilat em- 752 'blematic head which,` due to its shape and size, is seatedin the recess 6 and is held by `:from turning. "It is of such a thickness that it lies'in back "of the planefof theiace ofthe impact bar, thereby formin a bumperface without the usual protru ingclamps and xtures.`

The other ends oove l heade bolts 14. .As in the other types demg bar securely in horizontal ali ent AIliiwith the Vimpact bar 10 as shown in ig. 9.

A stillvfurther modified form of the invvention is'shown in Fig. 10. The ilnpact 'bar shown this figure is similar to that described above and shown in Fig. 7; there` used to simplify the description. The attaching bars are straight strips of spring steel set on edge with their ends bent to form an angle portion 1'6 which lits into the groove 6 in t e rear of the impact member 10 as shownin Fig. 11.` The angle portion 16 is secured by bolts 14 and is held in horizontalalignment with the impact memxber bymeans of the edges of recess 6 as shown in Fig. 12.

It is apparent from the above description that this type of bumper will allow for expeditious aembly andwill do away with .the use' of clamps for rigidly aligning the 'attachingbars with respect members orzmember of a bumper.

Itis also apparentthat this type of bumper will present a pleasing elect tothe eye.

Iclaim: y 1. In' a bumper of the type described, an impact bar having al longitudinal recess formed in one face thereof, said recess permitting the attachment and alignment of a fore, the same designating numerals will be.

to the impact and a bolt for securing said portion of said rear supporting bar to said impact bar in rigid horizontal alignment, said bar having a longitudinal protuberance on the other face thereof corresponding in location to said groove.

3. In a bumper of the type described an impact bar having looped ends thereon, said impact bar having a longitudinal groove formed in the middle thereof, a rear bar having its center portion bent forward and secured to the rear of said impact bar, the ends of said rear bar fitting snugly into the groove in said impact bar and being secured in rigid horizontal alignment therewith at each end by a bolt.

4. .In a bumper of the type described, an impact bar having a longitudinal recess formed in the impact face, said recess permitting the attachment and alignment of arear bar in said recess by one bolt at each point, of attachment.

5. In a bumper of the type described, an impact bar having looped ends thereon, said impact bar having a longitudinal groove formed in the impact face thereof, a rear bar having its ends secured in said groove in rigid horizontal alignment therewith at each end by a bolt.

In testimony specification.

whereof, I have signed this noLLm s. meson.
